My betta fish has been sick and I can't figure out what's going on. He is seeming to get better, but I want to be sure. I just put him in a 10 gallon tank 1.5 weeks ago and he has been so happy swimming all around. The water has been cloudy and I've changed 25% twice now to try to clear it up and followed the steps with the water conditioner, etc. The tank has a filter and a heater. I tested the PH, Nitrate, etc. and all was perfect after the first water change and mostly perfect after the second. He has been hanging out on the bottom of the tank and sometimes on his side and looked paler than usual. He has always been pale so it's hard to tell if his color is really gone. A couple of times he was breathing hard and not moving. He seems to be getting better and is now moving around, but will swim around for a bit and then go rest down at the bottom. I want to get ahead of anything that may be wrong, but I'm not sure if there is as he's moving, comes to see me and still eating. It looks like his fins are frayed a little and clumped - maybe? I'm not sure if it's from the filter, plastic plants (I know - I read that is bad after the fact) or if it's the onset
of fin rot. Any advice on what to do? And, the cloudy tank!?
